  • Method for delivering replacement rail ties using GPS techniques
    Patent number: 7437997
    Abstract: A method of efficiently delivering replacement railway ties for use in replacing ties that have deteriorated. GPS technology is used to obtain the GPS location of each tie that needs to be replaced. A tie train carrying replacement ties has a GPS monitor so that one or more ties can be unloaded at or near the location of each tie that requires replacement. A tie replacement crew can use a GPS monitor to locate each tie that requires replacement, and the crew can remove those ties and install a nearby replacement tie.

  • GPS controlled multiple source material application
    Patent number: 6526339
    Abstract: A GPS controlled multiple source material application or ballast spreading system includes tracking the position of a plurality of ballast hopper cars using GPS derived coordinates and controlling the opening of multiple ballast doors to spread ballast on desired sections of track for railroad maintenance. The process involves tracking the current hopper loads, the opened or closed state of the ballast doors, and the concurrent amount of ballast which has been spread on the desired track sections.
